Dr. Hiroshige is very polite and explains the procedures and gives some choices for treatment in advance. She does all cleaning herself -- which in my opinion is a bonus since you have an experienced dentist looking at you the whole time. She is more likely to notice problems than a hygenist. I had a lot of problems with my teeth and in my estimation she did very good work and charted an effective treatment plan.
The area nearby is also quite nice. There are a lot of good coffee shops so you can damage your teeth while you wait!!
If you are Japanese, Dr. Hiroshige is a bilingual both in Japanese/English and can explain treatment options in Japanese. This can be an added bonus for people from Japan since dental practices and typical problems there can be a little different than in the USA.
